Wheel Speed Sensor Circuit Failure - Right Front
This code indicates a problem with the right front wheel speed sensor circuit.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The right front wheel speed sensor isn't sending the correct information to the computer, which can happen if it's damaged or there's a wiring issue.
What the computer is actually seeing
The vehicle's computer expects a specific voltage signal (typically around 0-12 volts) from the wheel speed sensor as the wheel rotates. If the sensor voltage is too low or absent when the vehicle is moving, it triggers this code.
What a healthy reading looks like
Normal sensor output should show varying voltages (around 0.5V to 5V) when the wheel is spinning, depending on speed and conditions.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 11. Inspect the wiring and connectors at the right front wheel speed sensor for signs of damage or corrosion. If damaged, repair/replace as necessary. Check for proper connection.
- 22. Measure the voltage at the sensor connector with the ignition on but engine off. Expected voltage should be around 5V. If absent, check power and ground to the sensor. Repair as needed.
- 33. If the voltage is present, but the code persists, remove the wheel speed sensor and test it according to manufacturer specifications. If it doesn't meet specs, replace it.
- 44. Clear the code and test drive the vehicle to see if the code returns. If it does, check for any other related DTCs and inspect the ABS module for faults.
Common causes
- Damaged right front wheel speed sensor
- Faulty wiring or connector issues
- Bad wheel bearing affecting sensor alignment
- Poor connection at module or sensor
- Corrosion at terminals
Typical repair cost

Frequently asked questions
Can I still drive the vehicle with this code?
Yes, it is drivable, but the ABS system may not function properly, which can affect braking performance.
Will this code come back if I clear it?
It may come back if the underlying issue isn't fixed, particularly if the sensor is faulty or wiring is damaged.
Why does this code relate to ABS?
The wheel speed sensors are crucial for the ABS system to function correctly; they help monitor wheel rotation to prevent locking during braking.
